Ahhhh, it's stuck in my head for a few hours and i really couldn't find it, neither the lyrics on google, nor the song on youtube. It goes like this: "I'm stuck in the middle of, stuck in the middle of..." I have found, though, some songs with the words: "stuck in the middle", but none of them was the one i am looking for. Who sings it it's a man and it's an older song. It has a nice rhythm, too!
